post_merge_setup

Post-merge setup automation runs a project-defined script from the repository root to install packages, run migrations, and rebuild, then reconciles active workflows with repository configuration to prevent broken builds and stale CI state.

Workflow reconciliation stops workflows removed from configuration and restarts or syncs workflows that should be running after a code merge. You need it when repository configuration changes and your CI state must match the updated setup.

Post-merge setup execution runs the configured script with stdin closed and captures stdout, stderr, runtime duration, and exit status. It returns execution status and explicit setup or reconciliation errors for debugging and retry logic.

Config management reads and updates the post-merge script path and timeout values stored in repository configuration. This allows you to specify which setup script runs from the project root and how long it can execute before timing out.

CI workflows break after merges when dependency changes require installs or migrations that do not run automatically. Post-merge setup scripts execute these updates and reconcile workflows so the CI state matches the updated repository configuration.

Reconciliation limitations include explicit setup or reconciliation errors returned when scripts fail or timeout. The configured timeout value bounds execution, and captured stderr logs provide debugging information for retry logic when workflows cannot sync.
